BBP transition and the leading eigenvector of the spiked Wigner model with inhomogeneous noise

Leonardo S. Ferreira, Fernando L. Metz

The spiked Wigner ensemble is a prototypical model for high-dimensional inference. We study the spectral properties of an inhomogeneous rank-one spiked Wigner model in which the va…
